Abstract: The general objective of this study is to investigate the effect of project delays on the performance of construction projects in Gasabo District, Rwanda, specifically focusing of Zaria Court Project by Real Contractors Ltd. Statistical Package for Social Sciences (SPSS) version 25 facilitated descriptive and regression analyses, ensuring the generation of meaningful interpretations of the research findings. The R value of 0.797 indicates a strong correlation between the predictor variables (Decision making, Scheduling and Supply chain) and the performance of Zaria Court Project by Real Contractors Ltd in Gasabo District, while the R squared value of 0.635 signifies that 63.5% of the variance in performance can be explained by the independent variables included in the model. The Durbin-Watson statistic of 1.983 indicates that there is no significant autocorrelation in the residuals, which strengthens the model’s reliability. The significance of the model is confirmed with a p value of less than 0.05. The coefficients indicate that for each unit increase in supply chain, scheduling and decision-making, the performance of the project is expected to increase by 0.369, 0.187, and 0.409, respectively, when all other variables are held constant. The significance of each coefficient (p < 0.05) confirms that all independent variables have a statistically significant effect on the performance of the project. The paper recommends that Real Contractors Ltd staff should attend risk management training, suppliers improve inventory systems, and teams adopt technology.
